Device Overview
74CBTLV3253PW,118 is a Nexperia dual 1-of-4 multiplexer/demultiplexer bus switch in a TSSOP-16 package. For substitution or design review, the strongest comparison points are Device Function (dual 1-of-4 multiplexer/demultiplexer bus switch), Channel Topology (2 independent 1-of-4 mux/demux channels), Supply Voltage (2.3 to 3.6 V).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | dual 1-of-4 multiplexer/demultiplexer bus switch | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Channel Topology | 2 independent 1-of-4 mux/demux channels | Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. |
| Supply Voltage | 2.3 to 3.6 V | Defines compatibility with the available board power rail and required bias range. |
| Switch Connection Resistance | 5 ohm (manufacturer feature class) | Adds series resistance in the signal path and therefore affects voltage drop, insertion loss and signal integrity. |
| Exact Package | TSSOP-16 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Partial Power Down | I_OFF supported | Defines a selection-critical engineering characteristic that a compatible substitute must preserve under the stated conditions. |
Logic and Interface Selection Notes
Device Function is dual 1-of-4 multiplexer/demultiplexer bus switch. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. The channel topology is 2 independent 1-of-4 mux/demux channels; this defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide.
2.3 to 3.6 V is the stated supply voltage value. Defines compatibility with the available board power rail and required bias range.
At TSSOP-16, the exact package determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For switch connection resistance, 5 ohm is the approved value. Adds series resistance in the signal path and therefore affects voltage drop, insertion loss and signal integrity. Technical condition: manufacturer feature class. The partial power down is I_OFF supported; this defines a selection-critical engineering characteristic that a compatible substitute must preserve under the stated conditions.
